9453a8a7e6 - reuse the same vertex buffer data for all slices of a decal. 2016-02-01 21:50:55 +01:00

faa08410de - handle nocoloredspritelighting with 3D light splitter 2016-02-01 19:10:15 +01:00
Christoph Oelckers
2c55dcca27 - use hardware clipping to apply 3D lights to sprites. This solves all the problems with properly lighting models and billboarded sprites. 
- add some restrictions for the checks that exclude sprites which are too close to the camera. Most importantly, for clipping the first frame of a projectile, do not solely clip against the projectile's speed but use the player's radius as a limiting factor to avoid too large distances.

67fc35e738 - some cleanup of wall processing code. 
* removed SplitWall function
 * split PutWall into PutWall and PutPortal because none of the portal cases needs the overhead for normal walls.

9305cd86a0 - remove the GLWallLightEntry type. Everything it contains can be retrieved from the existing lightlist just as easily, and this approach avoids a lot of memory allocations. 
- removed the SplitWall profiling timer because all it measures now is an almost empty function.

53a389aafc - fixed: for untextured walls, the texture must be disabled before rendering. 
- fixed: untextured walls should never be passed to SplitWall.
- fixed: untextured walls should not be affected by dynamic lights (it's either fog boundaries or outsides of 3D fog volumes.)

9ce6a7932c - implemented rendering of 3D lights with clip planes. 2016-01-31 22:04:20 +01:00

5448b335c6 - rewrote render loop for walls. Not working yet. 2016-01-31 21:10:59 +01:00

f86535407d - forgot this. 2016-01-31 00:52:50 +01:00
Christoph Oelckers
1d9ab5c632 - clean out GLWall::SplitWall and instead of actually splitting the wall just attach a list of lights to it. 
Actual handling will be in the rendering function because this doesn't need multiple vertex transfers to the GPU. All slices can be drawn from the same buffer with different uniform info being set.

fc57180d7e - added necessary state to implement 3D light splitting using hardware clipping planes. 2016-01-30 23:01:11 +01:00

4a9b2bf76d - fixed: The stencil cap drawer did not properly advance the vertex pointer. 2016-01-30 01:08:11 +01:00
Christoph Oelckers
d037493ffe - fixed handling of FF_FADEWALLS on 3D floors. The problems with the old method became quite obvious in the demo map after the light list bug got fixed. 2016-01-29 17:13:14 +01:00

238990c871 don't leave any gaps in the used clip planes. 2016-01-27 12:32:39 +01:00
Christoph Oelckers
47db3252f4 - it's really not necessary to waste two clip planes for reflective surfaces because only one can be active at any time. 2016-01-27 12:30:55 +01:00

3c16a23865 - when rendering mirrors, discard subsectors lying behind them. 2016-01-27 12:02:43 +01:00

2657c08831 - fixed: stacked sector portals were not added to the render list 2016-01-13 21:33:27 +01:00

65022b780a - implemented 'copy portal to wall' linedef type. 2016-01-11 22:44:53 +01:00
Christoph Oelckers
196c9bc34d - cleaned up the skybox type detection logic. 2016-01-11 20:29:24 +01:00

ef7bcb3a66 - implement Eternity-Style flat and horizon portals. Not tested yet due to lack of material to work with. 2016-01-11 15:07:58 +01:00
Christoph Oelckers
7d2bbbd351 - fixed rendering of two-sided polyobjects that have their upper or lower textures exposed. 2016-01-05 18:59:32 +01:00
Christoph Oelckers
cc10fe9bc3 - fixed: The stereo3D code accessed the global 'viewsector' variable at a place where it no longer contained a correct value. 
- fixed: The same code did not exclude camera texture views from drawing the 2D overlay.

c8810db5fe - fixed: clipping swimmable against non-swimmable translucent 3D-floors was broken due to an incorrect flag check. 2015-12-24 16:34:00 +01:00

f9cbaef1df - fixed: Boom's Transfer_Heights did not work for upper parts in sectors with a sky ceiling. 
This incorrect check has been in the code for 12 years, unfortunately I have no idea anymore why it was added.

16cb4407a4 - disabled 'isVisibleToPlayerClass' check for dynamic lights affecting sprites. 
Calling this function in the inner loop of a time critical rendering function apparently wreaks havoc with the CPU instruction cache - even though the function doesn't do anything substantial.
This needs some more in-depth investigation why just having that call can increase sprite rendering time by a factor of 10 and more if there's many lights in view.

789dca2ab3 Refactor stereo 3d projection matrix calculations to use VSMatrix. 2015-10-31 07:46:36 -04:00

89328e685c Use eye->TearDown method to restore glColorMask. 
Restore assert in i_system.cpp that was interfering with my debugging.
Restore scoped colorMask-ing in gl_portal.cpp and gl_drawinfo.cpp.

b82d611936 Call EndDrawScene for each eye.

0874455faf Initial implementation of five 3D modes -- some bugs remain. 2015-10-30 20:51:35 -04:00
Christoph Oelckers
065b7f9ad2 - fixed: The CollectSectorStack functions had a local sector_t variable used by gl_FakeFlat which caused a stack overflow. Using the global one defined at the top of the file is ok here. 2015-05-29 12:03:50 +02:00

feeebf5265 - rework MD2 code for reloading/precaching of geometry data. 2015-04-12 18:26:52 +02:00

cf7cb4f00f - use hardware clip planes to split translucent walls and sprites by 3D floor planes. 
This method has the advantage that it also works for models, xy-billboarded sprites and walls that require complex splitting of the polygon. The old method using actual polygon splitting only works for strictly vertical data that could be trivially split in two.

bead3e046b - fixed weapon positioning again, after finding out that the first fix just worked around the actual problem: The entire coordinate calculation must be done in floating point with no integer math at all. Due to roundoff errors the stored int values needed for wall and flat placement significantly lack precision and with the high scaling factor that needs to be used for weapon HUD sprites these can easily become several pixels. After fixing this the border around sprite textures could be reverted to one pixel again. 
- fixed: The 'may not be expanded' state should be stored in the texture and reused later. This also needs to revalidate the material if it decides that expansion should be disallowed.

67334bfa2b - calculate weapon positions fully in floating point to avoid roundoff errors. 
- In order to get reliable results the empty border around scaled sprites must be the same scale as the sprite (i.e. 2 pixels for 2x scale and 4 pixels for 4x scale.)

Christoph Oelckers
a5a53c51e6 - fixed: The flat drawing code assumed that the first element of the light list originated from the sector itself. This had been true formerly but in some situations it no longer is. 2015-02-10 21:52:19 +01:00
Christoph Oelckers
00639121c0 - added the missed parts of camera roll in gl_scene.cpp. 2015-02-10 20:34:10 +01:00
Christoph Oelckers
8a9692c29f - fixed: The code which decided whether to clamp two sided middle textures used the texture size instead of the render size for the specific linedef, meaning that any per-sidedef scaling was ignored. 2015-02-10 20:16:25 +01:00
Christoph Oelckers
a8398e70b0 - fixed: The brightfog flag in the GL related map settings was never initialized. 
- fixed: brightfog should not disable colored lighting for the weapon sprite.

e6d59ec429 - fixed: with aspect ratio compensation in the view matrix it is necessary to adjust the view pitch for this because the playsim does not know anything about pixel ratio. 2014-12-31 12:04:55 +01:00
